UV-Resistant Polypropylene Pipe Fittings for Chemicals
Made of polypropylene, these fittings won’t deteriorate when exposed to the damaging effects of ultraviolet light and are suitable to use outdoors. They have the chemical resistance to withstand a wide variety of acids, solvents, and other harsh substances. Apply a non-hardening, plastic-compatible sealant to the male threads to prevent leaks. Tape or sealants with PTFE are not recommended for plastic-to-plastic threaded connections. When making a threaded connection be careful not to overtighten the threads. To prevent cracks and leaks, finger tighten the fitting, then wrench-tighten one to two turns.
Schedule 40 fittings have thinner walls than Schedule 80 fittings and are typically used in commercial and residential applications.
Schedule 80 fittings have thicker, stronger walls than Schedule 40 fittings for heavy duty, industrial chemical processing applications.
Warning: Never use plastic pipe fittings and pipe with compressed air or gas.
Sealants cannot be sold to Colorado, Connecticut, District of Columbia, Delaware, Illinois, Indiana, Massachusetts, Maryland, Maine, Michigan, New Hampshire, New Jersey, Northern Virginia, New York, Ohio, Pennsylvania, Rhode Island, or Utah due to local VOC (Volatile Organic Compounds) regulations.

High-Temperature PTFE Pipe Fittings for Chemicals
Extreme temperatures are no problem for these fittings—they’re made of PTFE, so they can withstand a wider temperature range than any of our other plastic pipe fittings for chemicals. They have the chemical resistance to stand up to acid and solvents. Fittings have thick, Schedule 80 walls for heavy duty industrial applications. The material won’t leach contaminates into the line, so these fittings are commonly used in high-purity processes, such as semiconductor and clean room applications. They have a super-smooth interior for unrestricted flow. Apply a non-hardening, plastic-compatible sealant to the male threads to prevent leaks. Tape or sealants with PTFE are not recommended for plastic-to-plastic threaded connections. When making a threaded connection be careful not to overtighten the threads. To prevent cracks and leaks, finger tighten the fitting, then wrench-tighten one to two turns. Fittings meet ASTM D1710 specifications and testing requirements for material quality.
Warning: Never use plastic pipe fittings and pipe with compressed air or gas.
Sealants cannot be sold to Colorado, Connecticut, District of Columbia, Delaware, Illinois, Indiana, Massachusetts, Maryland, Maine, Michigan, New Hampshire, New Jersey, Northern Virginia, New York, Ohio, Pennsylvania, Rhode Island, or Utah due to local VOC (Volatile Organic Compounds) regulations.

Plastic Pipe Fittings for Gasoline
Use these plastic fittings to connect gasoline fuel lines to machines and equipment. They have excellent corrosion resistance as well as high strength and impact resistance. Apply a non-hardening, plastic-compatible sealant to the male threads to prevent leaks. Tape or sealants with PTFE are not recommended for plastic-to-plastic threaded connections. When making a threaded connection be careful not to overtighten the threads. To prevent cracks and leaks, finger tighten the fitting, then wrench-tighten one to two turns.
Plugs with fluoroelastomer gaskets, also known as Viton® fluoroelastomer gaskets, ensure a tight seal. They also resist a wide range of chemicals, including benzene, butyl alcohol, and ethylene glycol.
Warning: Never use plastic pipe fittings and pipe with compressed air or gas.
Sealants cannot be sold to Colorado, Connecticut, District of Columbia, Delaware, Illinois, Indiana, Massachusetts, Maryland, Maine, Michigan, New Hampshire, New Jersey, Northern Virginia, New York, Ohio, Pennsylvania, Rhode Island, or Utah due to local VOC (Volatile Organic Compounds) regulations.

Plastic Pipe Fitting Plugs for Food and Beverage
- For Use With: Beverage, Dairy, Food
- Temperature Range: -30° to 140° F
- Specifications Met: ASTM D6778
These plugs are suitable for food and beverage applications and won’t impart tastes or odors to your product. They are acetal, which has excellent moisture resistance, so the plugs won’t soften or lose strength even in high-humidity environments. When making a threaded connection be careful not to overtighten the threads. To prevent cracks and leaks, finger tighten the fitting, then wrench-tighten one to two turns.
Warning: Never use plastic pipe fittings and pipe with compressed air or gas.
